#225 of 1521 transmission problems
Feb 10, 2008 (6:00 am)
I don't know about the cooler lines, but I have a 2006 1/2 truck that was shifting hard into 2nd and the check engine light would come on. They had to replace transmission at 28000. This transmission had to be repaired at 17000 also.
The dealer said that my transmission was full of metal shavings on all of the clutches.
#226 of 1521 K1500 4x4 Tranny clicking
Feb 11, 2008 (4:41 pm)
Saturday morning when I cranked up my 99 Chevy K1500 it lunged about a foot and half. It was in park but still it lunged forward. Hasn't done that again but it is making a clicking sound like a card in bicycle spokes when its in 1st and 2nd gears. When it shifts out to 3rd and 4th the noise quits. This is a 4 speed auto tranny. Is it dying on me? What could be causing the clicking noise. It's like something laying on the teeth on a gear.

I am taking my 06 in Thursday to Tucks in Hudson to take care of the hoses! It was in last week for the problem, butttt they did not have any hoses, they are on back order, because there are too many trucks out there with this problem...
Whats up with your glow plugs?

I just had the exact same problem. 08 2500 duramax chevy with 240miles. Truck said shift inhibited, was towed to dealer and the tranny had crumbled inside. I am under the impression they are fully aware of this problem but do not disclose it at purchase. I am considering taking this to the Attorney General with documentation and as many people as I can.

#230 of 1521 2007 Silverado tranny problem
Feb 19, 2008 (1:52 pm)
Yesterday, I was driving out to my lake house and when I stopped at a light. I heard a loud "POP" and then the engine began to race. I thought the tranny slipped out of gear so I put it in Drive and nothing, same for 3rd, 2nd and finally I got some movement out of 1st. I was able to get the truck out on the side of the road and check the fluid level(which was OK) and then I called for a wrecker. After hearing the wrecker would take 2 plus hrs, I decided to try and make it as far as I could in 1st. After about 1/4 mile with the engine racing and the truck going about 8-10 mph, all of a sudden, the engine slowed down(rpm) and the trans caught. From there on everything worked fine. Put the truck in (D) and drove home, about 35 miles. The next day, I took the truck to Chevy dealer, they checked the tranny and told me that they could not find anything wrong, no computer codes or anything. My truck is a 2007 with 21k miles on it. Any ideas as to what the problem was/is??? What do I do if it happens again.??? I like the truck and this is the first time anything has remotely gone wrong. I'm planning on pulling my boat to the Texas coast in the next couple of weeks and right now I'm a little gun shy about doing it.

from reading other forums, I believe your transmission thought it had a failure.
It went into limp mode, transmission goes to 2nd gear and you can limp home.
guess that's why they call it that.
Hate to say it: probably will happen again, you may not be so lucky next time, depending on your location.
since truck is so new, might have transmission flushed, pull pan and look for metal particles in oil or on magnet, change filter.
Install a good quality synthetic oil
worth a try!!

have heard so many having transmission problems after flushing. However, transmission is one of the most negelected maintenance items. Transmissions that have received normal maintenance do fine with flush.
I agree, if high miles, I would not flush, just drain oil and replace filter, clean any visible material/gunk in pan area.
replace with gm quality oil. about 6 qts.
again, in 10k you can pull pan change 6qts and you will have most of the oil in trans changed.
to change to synthetic oil you need to clean trans, this would require sometype of flush and clean before adding new oil.

We just as Maxwell said, It happened again yesterday and I barely got it to the dealer and he finally saw what I had said 2 days earlier. The tech put the diagnostic tool on it and guess what??? nothing...no codes at all, but there the truck was, engine running and the truck standing still in "D" and then in 3rd. The tech seemed very confused to say the least. I went by today, and they had the trans out of the truck and apart. Something about a 3rd gear failure.. They were to call GM today to get their input as to repair or replace the tranny. I told the service agent I wanted it REPLACED, but we will see. In all my driving of Chevys and GMC, this is the first time I've ever had any tranny problems. If the tranny is repaired, I'm feeling a little uneasy about keeping the one year old truck. Any feelings on whether I should get a new one or keep this one if the tranny is just repaired????

I wouldn't settle for a repair job. Back in the early 90's I had a trans failure on a '91 Nissan at 28K miles. They replaced with a new one no questions asked. Course it could've been rebuilt but it lasted till 128K miles when I sold the truck. Worse case I would settle for would be a rebuilt with an extended warranty on the trans.
